Application filed February 27, 1322. Serial No. 539,438.

T 0 all whom it may concern:

Be it known that I, Bonner R. heaven, a

citizen of the United Chicago, in the county Illinois, have inventedImprovement in Cars, ing is a specification.

My invention relates cars of the so-called wherein the bottom of States,residing at of Cook and State of a new and useful of which thefollowmore particularly to drop bottom, type, the car is formed, in

part, of doors hingedly supported on the car structure to in which theyclose for retaining therein the material be swung from a position thebottom of the car filled into the car, into a position in which thematerial may be discharged from the car.

In cars of the type referred to, it is neces sary that there be provideddoor-stops at the openings in the bottom which the doors extend, withthe margmal edges of of the car and at for co-operation the doors toeffect the desired closing of the openings when the doorsare shut, andit is one of my objects to provide which shall serve not but also as adoor-stop for door adjacent the enda one piece member only as anend-sill, the edge of the sill, it being my object in this connection toimprove upon structures as hitherto provided, to the end that theconstruction thereof may be simplified and be rendered less expensiveand be highly satisfactory in ther object is to pro door-stop, so shapedthat not become lodged, and

operation. A furvide a self-cleaning the material will retained, thereonin the dumping operation; and other objects as will be manifestscriptionz from the following de-.

In the accompanying drawing, I have illustrated my inventionlongitudinal, sectional by a perspective, view taken through one endportion of a material-transporting car of the drop bottom myimprovement, the

type and embodying particular construction of car shown being formed ofsidewalls, a portion of only one thereof being shown at l, end-walls aportion only of one of which is shown at 2,

which is shown at 8 and members extending fro car and disposed in spaend-sills one only of a series of cross no side to side of the icedrelation between the end-sills and forming the open bottom of the car,one of these shown at d, and doors,

cross members being one only of which is shown at 5, which would besupported in any suitable way, as for example, by flang- 1 ing theirlower edges as represented by the end-wall 2 as shownin the drawing, theprovided on this end-wall, for the purpose stated,- beingrepresented at6 and being secured to the upper horizontal portion 7 of the sill. 3, asby riveting it thereto represented at 8. The upper plate portion 7 ofthe sill extends inwardly beyond the wall 2 to a position inwhich itoverlaps adjacent marginal edge of the door 5, and thence inclinesupwardly, as represented at 9, toward the inner surface of the end-wall2 to which the latter is rigidly secured, as by rivets 10 extendingthrough this end-wall and through the upper flange the inclined portion9.

The portion 9 1s preferably of such in olination that in the dischargingof the.

material from the car through the open bottom thereof, the material willnot lodge thereon, whereby the structure is rendered self-cleaning.

It will be understood that the sill 3 will extend entirely across theend of the car and that the portion 9 which is located within'theinterior of the car will, by preference, extend the full width of thecar at the inner side thereof, and thus where the car is provided withtwo parallel series of doors 5 arranged at opposite sides of the centerline of the car, the doorstop portion referred to and shown as formedintegrally with the sill 3, will co-operate with the rear edges of bothof the adjacent end doors.

It will. be noted that the providing of a combined end-sill anddoor-stop as exit also aids in strengthening the structure and generallyimproves on such structures as hitherto provided.

lVhile I have illustrated and described a particular embodiment of myinvention, I do not wish to be understood as intending to limit itthereto, as the same may be variously modified and altered withoutdeparting from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:

1. A car having an open bottom and a door cooperating therewith, the carbeing formed with a combined endsill and doorstop.

2. A car having an open bottom and a door cooperating therewith, the carbeing formed with a combined end-sill and doorstep formed as an integralstructure.

3. A car having an open bottom and door cooperating therewith, the carbeing formed with a combined sheet metal endwall and door-stop.

4c. A car having an open bottom and a door cooperating therewith, thecar being formed with a combined sheet metal end wall and door-stop,formed as an integral structure.

5. A car having an open bottom and a door cooperating therewith the carbeing formed with a member of sheet metal forming a hollow end-sill withits upper portion extended inwardly and forming a doorstop.

6. A car having an open bottom and a door cooperating therewith, the carbeing formed with a combined end-sill and doorstep, the upper surface ofsaid door-stop portion inclining upwardly toward the inner surface ofthe end wall of the car.

'Z. A car having an open bottom and a door cooperating therewith, thecar being formed with a member of sheet metal forming a hollow end-sillwith its upper portion extended inwardly and forming a doorstop having atoward the inner surface of the end-wall of the car.

8. A car having an open bottom and side and end-walls, and a doorco-operating with said open bottom, the car being formed with a memberor" sheet metal forming a hollow end-sill with its upper portionextended inwardly beyond the adjacent end-wall of the car to form adoor-stop at the inside of the car, and formed with a portion whichinclines upwardly toward the inner surface of said end-wall and issecured to said end.

wall.

9. As an element of car-constructi0n a combined end-sill and door-stop.

10. As an element of car-construction a combined end-sill and door-stopformed integrally.

11. As an element of car-construction a combined end-sill and d0or-stopof sheet metal.
